[QUOTE="Arisley, post: 1388653, member: 67"] Instead of wiring like you have it, use the factory wiring to fire two relays. Use fresh battery power run through two fuses for the power feed through the relays. Each relay feeding one pump. I have my 5/8 draw straw cut on a 30º angle. I also notched it in four places. I am plumbing basically the same as you, except my filter bases have two feeds and two exits. On the pre-pump filter, I have one of the feeds plugged, on the post pump, I have one of the exits plugged. I am also running 5/8 inch line to the splitter and 3/8 inch from the splitter to each head. I run 1/4 inch from the heads to the regulator and use the factory 3/8 supply line for a return. I have my regulator set to idle at 65. At WOT, it will drop to 63. I ran it with one pump dead for about six months. Unless I went to WOT really fast, it would still hold 55 lbs. It freaks gasser guys out when they see a fuel supply line as big as a garden hose. Really freaks them out when with normal everyday driving, I still get 17 MPG. [/QUOTE]
